Researchers with the CAS Changchun Institute of Optics, Fine Mechanics and Physics show a silicon carbide (SiC) single mirror blank with a record-breaking diameter of 4.03m, which has passed the testing process for project acceptance, in Changchun City, Northeast China's Jilin Province, Aug. 21, 2018. The mirror blank is a vital component for creating a large-scale telescope, and the bigger it is the more capable it is of detecting visible light bands. (Photo: China News Service/Sun Zifa)
